Warranty Claim Tips
- Most insulation warranties are essentially material warranties — labor is almost never covered
- Spray foam warranties require installation by a certified applicator
- Keep your energy audit or blower door test results as baseline documentation
HomeScore Pro Tips
- Insulation rarely fails within warranty — the bigger risk is improper installation reducing R-value by 20–40%
- Rockwool is the only major insulation brand that doesn't degrade from moisture contact
